Application filed February 8, 1918. Serial 110.215.985.

To ZZ whom it may concern lie it known that I, BRUCE Folin, a citizen of the United States, and a resident of l'hiladelphia, in the county of Philadelphia and State of Pennsylvania, have invented cert-ain new and useful Improvements in Ventilating Storage-Battery Cells, of which the following is a specification.

'lhe principal object of the present invention is to provide for insuring proper ventilation of storage battery cells. more particularly submarine cells.

lhe invention will be claimed at the end hereof. but will be first. described in connection with the embodiments of it chosen for the sake of' illustration in the accompanying drawings. in Which- Figure i. is a top view of a cover embodying features of the invention.

Fig. 2, is a transverse sectional View of the same.

Fig. 3, is a. sectional view of the cover shown in Figs. 1 and 2, with a filling and ventilation fitting in place.

Fig. 4, is a section on the line 4-4 of Fig. 3.

Fig. 5, is a side view of the fitting detached from the cover.

Fig. 6, is a top View of a cover, showing a fitting in section, and illustrating a modification of the invention.

Fig. 7, is a vertical elevation of the device shown in Fig. 6.

Fig. 8, is a section on the line 8-8 of Fig. 7.

Fig. 9. is a view, similar to Fig. 6, illustrating another modification.

Fig. 10. is a section on the line 10-10 o-Fig. 11, looking in the direction of the arrows.

Fig. 11, is a section on the line 11-11 of Fig. 9.

Figs. 12 and 13, are sectional views taken at right angles to each other and illustrating a modification of the invention.

Fig. 14, is a section on the line 14-14 of Fig. 13.

Fig. 15, is a top View, artly in section, illustrating another modification of the invention and taken on the line 15-15 of Fig. 16.

Fig. 16, is a transverse sectional view of Fig. 15.

Figs. 17 and 18, are respectively a top view and a section of a cover embodying another modification of the invention.

Fig. i9. is a sectional view embodying still another modification of the invention.

Fig. 20. is a top plan view illustrating another modification, and

Fig. 21, is a section on the line 21-21 of Fig. 20.

In the drawings 1. is the cover below the under face of which is arranged a baille plate or )lates 2. In all the figures, except liigs. 6, and 8, the baille. plate or plates are vertical. li. c. at right angles with the cover. In Figs. (i, 7, and S, the baille plate is indicated at 2", and it is parallel with the cover or horizontal. In each of the figures there are Ventilating inlet and outlet passages respectively communicating with the spaces on opposite sides of the baille 2 or 2n and with the exterior' of the cell. The inlet and outlet passages are indicated in the construction in Figs. 15 to 21, at 3 and 4, and in the other figures they are the openings 3 and 4, which extend through thel unions or couplings 5 and G extending in opposed directions from the filling and Ventilating fitting which extends through the cover.Y As shown in Figs. 17 and 18, there is a iange 7 depending from the cover and encircling the opening 4 and merging into the baflies 2. This arrangement serves to insure good ventilation by prolonging the travel of the Ventilating fluid or air. The flange is shown as provided with opening 8. In Figs. 20 and 21, the vertical baiiie plates 2, are arranged in pairs and the passage 4 communicates with the space between the pairs, and the passage 3 communicates with the space outside of the pairs. The baiiies 2 extend approximately to the level of the electrolyte, when the latter is at its high level, and in that connection the openings 8 are useful but when the electrolyte is at a lower level, the openings 8 are not important. In the other figures similar provision is made by providing openings 8n in the filling and Ventilating fitting.

In Figs. 1 to 16, the openings 3 and 4 respectively communicate With separate open ended passages in the fitting and these passages are indicated in Figs. 1 to 14 at a and b.

In Figs. 1 to 11, the cover is provided with a floor 9, and in the construction shown in Figs. 9 to 11, the floor merges into a swell or bulge 9n in the baiiie plate 2. Above this fioor are ports 10 and through the floor is a second and similarfilling hole. The

of ribs or baiiies 2 and is connected with them.

vIn u se the `path of the, Ventilating fluid.

or air 1s rotracted by the bames and 1n this way gooventilation is insured. In connection with Figs. 1 to 14, an additional ad- Vantage is provided in that Ventilating tubes or pipes may-be connected to either the inlet or outlet, or both, ofthe filling and Ventilating fitting.

The described ittingis not claimed herein other than as showing examples of arrangements of air inlet and outlet in' connection with one or more ba e plates, but the fitting shown in Figs. 1 to 11, is made the subject-matter of my application serially numbered 215,986, filed February 8th, 1918.

What I claim is:

1. Improvements in Ventilating storage I assages :matinee battery cells comprising the combination of a cover, a baile-plate arranged below the under face of the cover, and Ventilating inlet and outlet passages respectively communicatin with the spaces on opposite sides of the aiile-plate and with the exterior of the cell.v y

2. Improvements in Ventilating storage battery cells comprising the combination of a horizontal cover, a vertical baie-plate depending from the cover, and Ventilating inlet and outlet passages respectively communicatin with the spaces on opposite sides of the aeplate and with the exterior of the cell.

3. Improvements in Ventilating storage battery cells comprising the combmation of a horizontal cover, a pair of vertical baile- 'plates depending from .the-cover, and passages communicating with the exterior of the cell and of which one communicates with the space between the baffle-plates and of which the other communicates with the space outside of the pair of lbaille-plates.
